Abstract: Techniques are described that can be used by a message engine to notify a core or hardware thread of activity. For example, an inter-processor interrupt can be used to notify the core or hardware thread. The message engine may generate notifications in response to one or more message received from a transmitting message engine. Message engines may communicate without sharing memory space.

Abstract: A method for vectorization of a block of code is provided. The method comprises receiving a first block of code as input; and converting the first block of code into at least a second block of code and a third block of code. The first block of code accesses a first set of memory addresses that are potentially misaligned. The second block of code performs conditional leaping address incrementation to selectively access a first subset of the first set of memory addresses. The third block of code accesses a second subset of the first set of memory addresses starting from an aligned memory address, simultaneously accessing multiple memory addresses at a time. No memory address belongs to both the first subset and the second subset of memory addresses.

Abstract: In one embodiment, a method for implementing quality of service (QOS) processing in a data bus interface. Each input read/write command is stored in a first-in-first-out queue. Each input read/write command includes a respective QOS value. In response to an input first read/write command having a QOS value higher than the QOS value of the read/write command at a head of the first-in-first-out queue, the QOS value of each of a first number of read/write commands is increased as each read/write command is removed from the head of the first-in-first-out queue.

The method comprises the steps of: analyzing the first software system, determining dependencies of the at least one first component of the first software system and acquiring relevant interface information; generating surrogates based on the dependencies and the interface information, which will be deployed in the first operating environment and in the second operating environment respectively, wherein the surrogates allow the second software system to invoke service provided by the at least one first component in the first operating environment and allow the at least one first component to invoke relevant service provided in the second software system.

Abstract: Disclosed herein are systems, methods, and computer readable-media for obfuscating code. The method includes extracting a conditional statement from a computer program, creating a function equivalent to the conditional statement, creating a pointer that points to the function, storing the pointer in an array of pointers, replacing the conditional statement with a call to the function using the pointer at an index in the array, and during runtime of the computer program, dynamically calculating the index corresponding to the pointer in the array. In one aspect, a subset of instructions is extracted from a path associated with the conditional statement and the subset of instructions is placed in the function to evaluate the conditional statement. In another aspect, the conditional statement is replaced with a call to a select function that (1) calculates the index into the array, (2) retrieves the function pointer from the array using the index, and (3) calls the function using the function pointer.

The method comprises receiving, at a USB port, first identification data that includes a generic device class code and a vendor identifier. Receiving the first identification causes one of enabling interaction with a peripheral device in accordance with functionality specified by the generic device class code if the host device does not support software associated with the vendor identifier, or sending, at the USB port, a query to the peripheral device if the host device does support software associated with the vendor identifier, the query sent to determine whether the peripheral device supports at least one function different from the functionality specified by the generic device class code.

Abstract: In one embodiment, to determine what tasks may be offloaded to a peripheral hardware device (e.g., to be performed in hardware on the peripheral device, rather than on the CPU(s) of the host computer), an indication from the at least one peripheral hardware device may be provided, without the peripheral hardware device first being queried to determine the task offload capabilities provided by the peripheral hardware device. In one embodiment, a large packet that includes a plurality of extension headers may be offloaded to the peripheral hardware device for segmentation. An indication of the offset where the extension headers end may be provided in connection with the large packet. In another embodiment, a packet with extension headers that come before an encryption header in the packet are not offloaded to peripheral hardware device for encryption, while packets with no extension headers before the encryption header may be offloaded.

Abstract: According to this invention, when initialization of a storage medium such as a flash memory is erase of the data area, the processing can be stopped. When the processing is stopped, at least initialization of the management area has been completed, and processing using the storage medium can be executed. If erase processing is not stopped but proceeds to the end, no erase processing need be performed in writing new data, and high-speed write is promised. For this purpose, when complete formatting is designated, the management area of the file system is first initialized. Then, erase processing for the data area of the file system is executed by a predetermined block size. If it is determined that stop is designated during the data area erase processing, the processing ends, but the management area has already been initialized.

Abstract: The disclosure provides a system and a method of processing keystrokes entered on an electronic device. The method comprises: monitoring for activation of two or more keys on the keyboard; evaluating whether the activation of those keys occurs within a set window of time; evaluating locations of those keys. After these evaluations, if the keystroke conflict is determined to not have been produced then characters for those keys are generated in order of their activations. If the keystroke conflict is determined to have been produced, then the method arbitrates between those keys to select a key utilizing a dictionary to automatically determine the key to be selected. In the dictionary, its entries are related to each of those keys combined with any previously entered keystrokes. The method then processes the selected key to generate on a display one character, which is associated with the selected key.
